33-3967XF-05-0150

Antennas RF Overview

The Calian 33-3967XF-05-0150 is a Tallysman Accutenna embedded, active dual-feed patch antenna designed for precision triple-frequency positioning. It operates across L1, L2, and L5 GNSS bands with center frequencies at 1.209GHz and 1.5655GHz. The unit features an integrated Low Noise Amplifier (LNA) and pre-filter, providing gains of -1.5dBic, 2.5dBic, and 4dBic. It utilizes an MCX right-angle plug connector with a 150mm cable length. The antenna supports BeiDou, Galileo, GLONASS, and GPS systems, offering a VSWR of 1.8 in a low-profile base-mount configuration.

Antennas RF Procurement Notes

Verify the specific ordering suffix to confirm the exact cable length and connector orientation, as variations exist within the TW3967XF series. Ensure compatibility with the host system's RF interface requirements before procurement. Confirm that the integrated LNA power supply specifications align with the target application's voltage and current capabilities to prevent operational failure.

Antennas RF Selection Notes

Select this component when triple-band L1/L2/L5 performance is required alongside a compact form factor. The active dual-feed design distinguishes it from passive alternatives, offering enhanced sensitivity for challenging environments. Consider the MCX right-angle connector for board-level integration where space is limited. Validate that the system can accommodate the integrated LNA power requirements and thermal characteristics associated with active antenna elements.

Antennas RF Part Context

This model belongs to the Calian Tallysman TW3967XF Pre-Filter Series, part of the broader Accutenna family. These antennas are engineered for high-performance navigation applications where signal fidelity is critical. The series emphasizes robustness and precision, catering to industries demanding reliable satellite positioning data in dynamic or obstructed conditions.

Antennas RF Replacement Considerations

Direct substitutes include other models within the TW3967XF series, such as 33-3967XF-05-0150 variants with different cable lengths. Cross-compatibility requires matching the dual-feed active architecture and MCX connector type. Verify that any replacement maintains the same L1/L2/L5 band coverage and gain specifications.
